Existing fixation modalities for Jones type fifth metatarsal fracture fixation pose high rates of complications and nonunion

Jones type fifth metatarsal fractures pose a challenge to the foot and ankle surgeon, given documented high nonunion rates as well as high complication rates including hardware prominence, nerve injury, and screw breakage for existing treatment modalities including screw and plantar plate fixation. We call for the design of innovative Jones-fracture specific implants which contour to the natural curve of the fifth metatarsal. Future research should aim to expand upon existing literature for Jones fracture fixation and evaluate efficacy of novel implants which are designed to address unacceptably high complication rates for existing treatment modalities.     

Leading together towards a stronger ‘us’: An experimental test of the effectiveness of the 5R Shared Leadership Program (5RS) in basketball teams

ObjectivesLeadership has been suggested to be a key factor in gaining a competitive advantage as a team, with shared leadership being a better predictor of team functioning than vertical leadership. Although the benefits of shared leadership are well-documented, evidence about how to implement a shared leadership structure remains sparse. This leaves coaches with three key challenges: (1) identifying the best leaders; (2) defining what roles those leaders should fulfill; and (3) developing their leadership skills. Solutions to these challenges have been proposed in the 5R Shared Leadership Program (5R^S) — a leadership development program that seeks to implement an effective structure of shared leadership within sports teams.DesignTo test the effectiveness of 5R^S program, we conducted an experimental-comparison group intervention in which eight national-level basketball teams (N = 96) completed a questionnaire at two points in time (i.e., pre- and posttest). The teams in the intervention condition completed the 5R^S program, in which we identified the leadership structure in their teams (through Shared Leadership Mapping), appointed the best leaders in their leadership role, and then developed their identity leadership skills.ResultsThe results revealed that the 5R^S program was successful in strengthening athlete leaders’ identity leadership skills, and as a result also team members’ identification with their team. Furthermore, in contrast to athletes in the comparison condition, athletes in the 5R^S condition were able to maintain their levels of intrinsic motivation and commitment to team goals, while also reporting improved well-being.ConclusionsThe present study provides encouraging evidence that, by implementing a structure of shared leadership and by promoting athlete leaders’ identity leadership skills, the 5R^S program is able to improve the team’s functioning and the well-being of its members.     

Insufficient knowledge and inapproriate physiotherapy management of Relative Energy Deficiency in Sport (RED-S) in lightweight rowers

ObjectiveTo investigate the knowledge and management of Relative Energy Deficiency in Sport (RED-S), from the perspective of lightweight rowers and physiotherapists.DesignSemi-structured individual qualitative interviews.MethodsPhysiotherapists who had worked with lightweight rowers, and current and former lightweight rowers (who had experienced at least one symptom of RED-S), undertook audio-recorded semi-structured telephone interviews. An inductive thematic analysis was performed, facilitated by NVivo software.ResultsTwelve physiotherapists (n = 6 females, 1–20 years of experience managing lightweight rowers) and twelve lightweight rowers (n = 8 females, 1–8 years lightweight rowing experience, intermediate to elite/international level) were interviewed. Five key themes were identified: insufficient knowledge of RED-S, inadequate RED-S education, inappropriate management of RED-S, referral to other health professionals, prioritising performance over health. Participants provided suggestions for improving knowledge and management of RED-S in lightweight rowers, including formal physiotherapy education and training, and targeted education for athletes and coaches.ConclusionsThere was a significant lack of awareness of RED-S amongst physiotherapists and lightweight rowers. Most physiotherapists were not confident discussing or managing RED-S in athletes, and lightweight rowers were dissatisfied with the management they received. Improving RED-S education for physiotherapists and athletes may have important health implications for lightweight rowers.

Australian football players experiencing groin pain exhibit reduced subscale scores of Activities of Daily Living and Sport and Recreation on the HAGOS questionnaire: A case-control study

ObjectivesTo report normative responses to the HAGOS questionnaire for Australian football players and to determine whether any of the HAGOS questionnaire sub scales can differentiate players with and without groin pain.DesignCase-control.SettingClinical setting.ParticipantsProfessional (n = 66) and semi-professional (n = 9) Australian football (AF) players with current groin pain (n = 16) and controls (n = 57) without current groin pain.Main outcome measureThe HAGOS subscales were compared between players with and without groin pain using the Wilcoxon rank-sum test with effect sizes (ES) calculated. Floor and ceiling effects were examined. A post-hoc factor analysis was undertaken.ResultsParticipants with current groin pain showed lower Physical Function of Daily Living (PFDL) and Physical Function in Sport and Recreation (PFSR) subscale scores (p < 0.05, ES: 0.77 and 0.90 respectively). Any groin pain (current and/or historical) lowered the Pain and Quality of Life (QOL) subscale scores (p < 0.05, ES: 0.38 and 0.72 respectively). Factor analysis showed 8 significant factors with one main factor identified representing items describing forceful activities (Eigenvalue = 18.02, Proportion = 0.49).ConclusionsThe HAGOS can distinguish AF players with current groin pain in the PFDL and PFSR subscales but not in the other four subscales. Any current or historical groin pain lowers scores on the QOL and Pain sub scales.Level of evidenceAetiology, Individual Case-Control Study, Level 3b
